Thinking about whether you need to get a Vit C supplement?
Though supplements are generally safe, overdosing on Vit C supplements may in fact bring more harm than good. Before getting a Vit C supplement, make sure to check out the dosage! Most vit C supplements contain 1000mg/serving. Therefore, overdosing is likely to happen.
We strongly encourage you to get your Vit C from your diet because it’s quite impossible to overdose on vitamin C through food. Fruits and vegetables also offer other nutrients than just vit C.
你在想要不要買維他命C補充劑嗎？
雖然説補充劑大都安全，過度服用維他命C補充劑帶來的弊會多於利。在買維他命C補充劑之前，一定要知道服用劑量！大部份的維他命C補充劑，每份含有1000毫克。所以過度服用的情況是有可能發生的。
透過進食而過度攝取維他命C是不太可能的，所以我們非常鼓勵你從日常飲食中攝取維他命C。水果和蔬菜也能提供維他命C以外的營養。
